GAGE-FRAME.

SPECIFICATION forming part of Letters Patent No. 761,954, dated. June1904.

Application filed April 14, 1904.

T0 (LZZ whom, it may concern:

Be it known that I, FRANK J. GEBI-IARDT, a citizen of the United States,and a resident of Cleveland, county of Cuyahoga, State of Ohio,

. have invented certain new and useful Improvements in Gage-Frames, ofwhich I hereby declare the following to beafull, clear, and exactdescription, such as will enable others skilled in the art to which itappertains to make and use the same. I

This invention relates to improvements in gage-frames for cutting clothstrips of predetermined width used in connection with any suitablecutting-tool; and the objects of the invention are to provide a devicefor this purpose whereby speed and accuracy of work can be obtained and.unvarying certainty in the straightness of the work and width of the rc-I sulting strips.

The invention consists in the rectangular frame over which the cloth tobe out is laid, a movable transverse bar which serves for a guide to thecutting-tool, and in the adjusting mechanism therefor by means of whichthe bar is advanced to provide for the cutting of each successive stripfrom the cloth and returned thereon, and in the various details ofconstruction, as hereinafter described, shown in the accompanyingdrawings, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of thecompletc'device, portions of the frame being broken away tov reduce thesize of the figure. Fig. 2 is an enlarged plan View of one corner of theframe, showing the movements of the mechanism of one side for advancingthe bar. Fig. 3 is a side view of the same mechanism. Fig. 4 is a planview of one corner of the other side. Fig. 5 is an enlarged side View ofthe ratchet device. Fig.

device mounted upon the end of the transverse bar and the side bar andguide-rod in trans verse section. Fig. 7 is a perspective view of theratch ets.

In the views, 1 is a rigid four-sided frame of flat bars securedtogether or integral. Upon this frame on either side are mounted therods 2 and 31, which are secured rigidly 1n supports 3 at either end. Onone side a plate 4, conwidth.

$eria1No. 203,093. (No model) nected to the transverse gage-bar 5, ismounted upon the side of the frame 1 and is guided thereon by thedepending flanges 6. Upon this plate is secured the vertical stop posts7, through openings in which the rod 2 passes. It is by means of thisrod and accessory mechanism that the gage-bar is manipulated in thefollowing manner:

Upon the plate 4 is placed a graduated scale Sin divisions of space,such as an inch and fractions thereof, and a plate 9, provided with astop edge 10 at right angles to the adjacent rod 2 and with a pointer11, is adjustably secured to the plate 4 by means of a slot 12 and screw13. At the outer limit of the scale is placed the clamping-lever 14,which is provided with an opening 15, which loosely encircles the rod 2.This lever is prevented from moving farther outward along the rod by thesecond stop-post 7, against which it abuts, and a spring 16 on the rodnormally holds it in its position. A solid block 17, secured to theplate 4, is placed at the inner limit of the scale and serves as a guidefor the pointer-plate and also serves to move the entire plate forwardwhen grasped, together with the free end of the lever 14. This isaccomplished as follows: The pointer being set to give the width ofcloth strip desired, the lever extremity and block 17 are grasped, andsince the lever will instantly grip. tightly the rod the plate 4 willmove forward until the edge 10 comes into contact with the I I edge ofthe*lever.14.- This act is only performed at one side of the frame, andthe plate 4 is brought forward, thus bringing with it the gage-bar 5,against which the cutting tool is guided. As soon as the lever and edge10 coincide the lever is. released and the spring 16 immediately throwsout the lever 14 again until it strikes the second stop-post 7. This actis repeated again and again, a strip being out every time and all stripsof perfectly even To expedite the cutting, the cloth in as manythicknesses as desired is simply laid over the frame, as seen in dottedlines in Fig. 1, and each cut made by a tool, such as the circularcutters now in use, which moves along the gage-bar 5. The transversedotted lines show the width of the strips as they are consecutively cutfrom the cloth, the bar 5 moving up each time an equal space by thescale. As the plate I moves up the guides, carrying the gage-bar 5 withit, it is prevented from slipping back by means of the ring-shaped latch20, which encircles the rod and has its lower edge set in the recess 21in the upper surface of the plate. The upper end of this latch isnormally moved forward by means of spring 22 on the rod, so the latchwill grip the rod and prevent any backward movement. When, however, itis desired to move back the bar 5, the latch is placed in the verticalposition, so as to release the red, when the plate 4: and bar are freeto move. This is done by means of the cam 23, pivoted on the support 24on the plate, Which frees the latch until it is desired to move the barback again. These movements to push the plates and bar forward and torelease the ring-latch are easily made, the plate being adjusted by onehand. In the meantime the other end of the bar 5 moves simultaneouslywith the end just described and to maintain its progress exactlycommensurate with the other end a ratchet device is employed similar tothat shown in the detail in Figs. 5, 6, and 7. Here 30 is a verticalplate secured to the end of the bar 5 just outside of a fiat rod 31,corresponding to the rod 2 on the other side of the frame 1, underneathwhich the bar 5 passes. Upon this plate are pivoted the pawls 32 and 33,which engage a sawtooth raek 34 upon the side of the frame and preventany backward movement, while permitting perfectly free forward movement.When it is required to push back the bar 5 to the starting-point, thepawls must be simultaneously released from the rack, which isaccomplished by means of the vertically-moving block 35, which issaddled over the plate 30 and is pressed down upon the rearwardextensions 36 upon the pawls by means of a lever 37, which is pivotedupon a vertical extension of the plate 30, thus raising both pawls fromengagement with the rack. When raised, a spring-pin 38, entering a hole39 in the lever 37, keeps the pawls out of engagement with the rackuntil it is desired to start again. A spring LO raises the plate orblock 35 when released by the lever. 41 is a guide for the block 35. Astop-pin 4L2 prevents the lever from rising too high.

The advantages of the ratchet device are great, since with this additionit is unnecessary to duplicate the moving device shown on the other sideof the frame. In operation the pawls move along the fine surface of therack as fast as the bar is moved forward and prevent any backwardmovement until they are raised. Again, it would be very diificult tooperate simultaneously the releasing-catches of the moving device ifduplicated on both sides of the frame, especially if the frame were verybroad, since it would be hard to reach far enough to operate one witheach hand.

Having described my invention, what l claim as new, and desire to secureby Letters Patent, is-

1. In combination with the four-sided frame between the sides of whichthe cloth is laid, a transverse bar adapted to serve as a guide for thecloth-cutting device, means for guiding the same on one side bar of theframe, for advancing the same a succession of times through apredetermined equal space each time, and means for locking the bar onthe forward movement on that side to prevent the backward slip while thecloth is being cut, means for releasing the same to draw back the barwhen the limit of the forward movement has been reached, and a rack onthe other side of the frame, and ratchet device upon that end of thebar, substantially as described.

2. In a device for the purpose described, a four-sided frame, a platemounted slidingly upon one side bar of the frame, a trai'isverse barconnected with the plate, a scale on said plate, a finger-operatedclamping device. to move such plate through a predetermined space on thescale, means for releasing said clamping device, a latch adapted tonormally prevent the return of said plate and connecting-bar, and a rackon the other side of the frame, and ratchet device on the other end ofthe bar, substantially as described.

3. In a device for the purpose described, a four-sided frame, betweenthe sides of which the cloth is laid, a transverse gage-bar, a platesecured to one end thereof mounted upon the side bar of the frame, andfree to slide longitudinally thereon, a longitudinal guide-rod securedupon one of said side bars at the outer ends thereof and passing oversaid plate and end of the transverse bar, blocks upon said plate throughwhich said guide-rod passes, a scale upon the plate, an adjustablestop-plate adjacent to the scale, a clamping-lever upon the rod, looselyengaging the rod, and a. spring upon the rod engaging the lever thereon,and means for preventing the irregular movement of the other end of thebar.

4. In a device for the purpose described, a four-sided frame, betweenthe sides of which the cloth is laid, a transverse bar, a guideplate forone end of the bar adapted to move longitudinally of one side bar of theframe, a rod mounted on the ends of the side bar and passing over saidside bar and guide-plate, a clamping-lever upon the guide-plate, agradir ated scale adjacent to the stop-plate, a spring on the rod, astop on the guide-plate engaged by one end of said spring, the other endof which engages the lever, and a stop on the guide-plate engaging thelever and limiting its forward movement, substantially as described.

5. In a device for the purpose described, a four-sided frame, atransverse bar mom'ited in longitudinal guides on the side bars of theframe, a rod mounted longitudil'lally on one side bar of the frame, andpassing over said transverse bar and guide, a stop-plate and graduatedscale on the guide, a gripping detransverse bar from backwardmovement,sub- I stantially as described.
